...because I've seen too many things made out of acrylic warp when exposed to temperature and humidity differentials. Usually, the thicker the acrylic is the worse the warping is. The 1/8 inch stuff is the most resistant that I've seen because the heat passes through much quicker and it's thus less susceptible to the warping but the 1/4 inch and 1/2 inch stuff is horrendous. In my experience having a Neodesha cage with a single 1/4 acrylic panel/door on a cage at work it suffered major warpage from only having a high 80s F temp inside the cage and a low to mid 80s temp outside the cage. The door would steadily warp farther inwards until you couldn't get it to close because the panel would flex too far into the cage if you tried to open it. We'd take the panel out and lay it down on a table for a couple weeks and it'd slowly flatten out so it could be used again, but within a couple weeks it would bow inwards again because of the differential. I think with the hotspot you want to shoot for you're going to see warping for sure.

Big animals, little animals, plants - right down to the sea itself. We need them, not just for their own sake, but because all this has to be here for everybody forever. Only one thing is certain: if we are to preserve our environment and save this priceless wildlife we need much, much more knowledge.
